iRobot Roomba® 770 Full Specifications

Roomba uses a patented 3-stage cleaning process to vacuum your carpets, hardwood, tile and laminate floors on its own, automatically adjusting to different floor surfaces as it moves through your home. Roomba 770's cleaning features include:

Advanced Cleaning Head: Designed with pet owners in mind, the new cleaning head provides superior performance for picking up pet hair, dirt, dust, allergens and more

AeroVac™ Series 2 Bin: Employs a powerful vacuum to vigorously pull debris and hair off brushes into the bin. The distributed air collection and clog-resistant design of the AeroVac Series 2 Bin optimizes vacuum effectiveness and dirt and hair packing efficiency.

Clean under the bed and other hard-to-reach areas.
Roomba provides comprehensive cleaning coverage – vacuuming in tight spots, under and around furniture and along baseboards. Roomba 770 features:

Persistent Pass Cleaning Method: Employs a back and forth cleaning pattern to apply elbow grease in areas where it senses excessive dirt

Every home is different.iAdapt Technology monitors the cleaning environment more than 60 times per second, using multiple sensors (like cliff detection) and dozens of behaviors (including wall following) to clean your home. Roomba 770 adapts to your home using:

Molded Soft-Touch Bumper: Cushions the contact made between Roomba's bumper and walls, furniture and other objects, protecting household items while it cleans

Dirt Detect Series 2: Uses optical and acoustic sensors to find dirt and debris, performing concentrated cleaning in the dirtiest areas and ensuring the whole floor is clean

Less work for you.Roomba knows which areas to clean – and those to avoid. Auto Virtual Wall® barriers emit an infrared beam that Roomba won't cross, keeping the robot in the rooms you want to clean and out of the ones you don't. Plus, Roomba charges itself, going back to its Home Base® to dock and recharge between cleanings. More 770 convenience features include:

Extended-Life Power Management: Roomba 770 uses sophisticated power management software to deliver up to 50% longer battery life than previous Roomba generations, ensuring hundreds of cleaning cycles under proper use

On-Board Scheduling: Cleans when it's convenient for you, up to 7 times per week

I purchased this product because I work full-time and have a large home to clean on my own. I also have a couple of dogs and found myself vacuuming twice a week or more sometimes. I had high hopes for the Roomba. This model had good reviews and I thought how wonderful it would be to have help vacuuming the floors.

Pros:-For a small vacuum, it picks up pretty well. -It does a good job picking up pet hair and dirt on my wood floors. -Sort of hands free (except when it get's stuck under furniture)

Cons:-Every time it switched from wood floor to area rug it left a big pile of dog hair behind. -It couldn't handle my plush area rug at all. It got stuck and told me to move it. -It got stuck under furniture easily, even when I tried to use the virtual wall. -I had to empty the debris bin frequently.-It didn't transition well between different flooring.

Out of my other Roombas, this one ranks #4. Wlhile my 770 which I call Iris, is a decent robot, it has a few drawbacks. It must have a clearance under furniture greater than or equal to 3.6 inches. It seems random compared to other robot vacs such as my Neato Botvac which maps the room. It also makes its way around by bumping into things. It could also use a stronger motor. It's a great vac, but it can't replace your upright. Now on to the pros. It has a potent cleaning system. The brushes pull up the carpet to a fluff, and clean reasonably deep into the carpet, and it cleans amazingly on hardwoods. One problem iRobot has addressed is the fact that the brushes are approximately 98mm away from a wall's edge. They fixed this with the fast spinning fiber optic sweeper arm which shoves dirt in front of it. Now for my tests. I vacuumed with my Shark and dumped the bin onto the floor and spread it out. The dirt detect feature sensed it and cleaned all of it. Another test I have performed is pouring a few steel BBs on the hardwood and it picked up all of them. I have more tests planned later. The maintenance on the Roomba (as with all of them) is relatively easy. Cleaning the whole machine is really easy (for me, at least). Putting it together is foolproof, right down to swapping wheel motors. Overall, great vac, easy to use and maintain, but, like all Roombas, it can't replace your upright.

I have many responsibilities, leaving me little time for cleaning. I looked for this to reduce my cleaning load, and it has done so to my satisfactionl. I do a couple of rooms at a time; either carry or navigate to the room in question, set down a virtual wall or two, then turn it loose while I work on something else.

The first time I used it, I had to clean out the bin halfway through the room because it picked up so much cat hair. After that, it is usually full around the time it finishes. I have a lot of area rugs, some with fringe. It does an excellent job of cleaning both the rugs and the hard surfaces. I have have never had an issue with fringe or power cords getting pulled in, something I can't claim about my upright vacuum.

It's worst performance is along the borders between area rugs and hard floors. The rugs are thick enough that there is a narrow gap on the hard floor where the suction is insufficient to get it all due to the elevated hight of one side of the Roomba. Sometimes it cleans it well anyway because the little corner brush will sometimes fling the bits of hair or debris away from this gap so it can be picked up somewhere else. But it sometimes misses these. When it does, I ignore it, and it will often catch it the next time I sweep.

It actually does better than my Hoover along baseboards and under furniture. I would use the attachments to manually get at those areas. But due to the difficulty of reaching them, I typically did a poor job of getting them clean. The Roomba actually does far better than I ever did on these areas. And I was scared to look under the bed and some other furniture for what I might find. But the Roomba attacked them fearlessly, and cleaned it all right up. I am very happy with it.

I then turned it loose, with some trepidation, on my filthy screened-in porch. Now, it looks better than it has since I spent three hours cleaning it up a couple of years ago.

Bought it on sale about a month ago and Robbie has been great doing a daily sweep/vacuum of our tile and hardwood floors.with a Newf dog and a nearby beach, Robbie has his work cut out for him but always surprises us as to how much he picks up oh his daily rounds.. Summer is giving him a work out. Very happy with Robert.

I am more than pleased with my iRobot. It does everything I want and then some. I am amazed at what it is picking up, even a wire twist tie. It spent a while under my bed and found a nail polish, a fridge magnet ( from my grandson) and a lost phone charger! I locked it in a room and let it play away for a while and found him in a walk in closet. He gets into every space.He is so easy to use, clean, recharge.I find myself just watching him rather than TV!Notice he's a male, just because.have a large dog, a cat and 2 messy birds,all who sleep inside on carpet and their room has never looked cleaner.I come home from work and just set him in a room for 30 minutes and enjoy the easily cleaned floors. It has given me a greater sense of joy in my home already.

I had surgery,and no one to do the cleaning. My husband bought the Roomba so the house would always look good. I programed the iRobot Roomba and it cleans at the same time and days without worrying if I have time to vacuum. I do not have to be home while the Roomba is cleaning. This is the best thing I could have ever owned.

We have two dogs and two cats. Our housekeepers come once a week and by the time they come the floor is taken over by hair. Vivian has been a real champ in cleaning up the hair in between visits. I would recommend it to anyone. If I had any complaint the bin is too small.
